Embodiment Construction

[0083] The present invention provides a method of determining the peel energy between a first layer (1) and a second layer (2) of a laminate (9) of composite material by a layup machine comprising an end effector (10). Both the first layer (1) and the second layer (2) are formed from material supplied by the laying machine and deposited or laminated by the end effector (10) of the laying machine.

[0084] To determine the peel energy, the second layer (2) is at least partially separated from the first layer (1), and for this purpose at least one component of the end effector (10) is displaced, thereby imparting displacement to the composite material, which In such a way that the second layer (2) is pulled to at least partially separate from the first layer (1).

[0085] Figure 1 to Figure 2 An end effector (10) of a tape / tow laying machine according to the present invention is shown, in particular, figure 1 The end effector (10) depositing the composite material (tape / tow) ...

Abstract

The invention relates to a method for determining the peeling performance by means of a laying machine and a laying machine. In particular, the invention relates to the automatic manufacturing of composite laminates for structures, preferably for aircraft structures, by using a laying machine. More specifically, the present invention relates to a method for determining the peel energy between layers of a composite laminate by a laying machine. The invention also relates to a laying machine for carrying out the method.

Description

technical field [0001] The present invention relates to the automatic manufacture of composite laminates for structures, preferably for aircraft structures, by using a lay-up machine. More specifically, the present invention relates to a method for determining, by a layup machine, the peel energy between layers of a composite laminate. The invention also relates to a laying machine for carrying out the method. Background technique [0002] The ability of a material to adhere to itself (eg, between its layers or to a solid surface) is known as tack or tack. This capability is a relevant property for a wide range of industrial applications and materials. In particular, this ability of a material to adhere to itself or to another surface is an extremely important property for the manufacture of fiber-reinforced composite laminates (also referred to as composite laminates). These composite laminates are made by automatic tape laying (ATL) machines or automatic fiber laying (A...
